The midpoint is calculated by taking the lower bound of the reported range plus the upper bound, and dividing by two. For example, if an asset is reported in the $15,001 – $50,000 range, the midpoint used would be $32,500.5 (the average of 15,001 and 50,000). In cases where the disclosure uses an open-ended top category (for instance, some forms list \"Over $50,000,000\" as the highest category for an asset value, with no upper limit), we will assign a value of $50,000,001 for that asset.","image":null,"icon":null,"outcomes":["Yes","No"],"outcome_prices":[0.016,0.984],"probability":0.016,"spread":0.006,"active":true,"closed":false,"start_date":"2025-05-10T14:00:00Z","end_date":"2026-12-31T15:00:00Z","closed_time":"2026-12-31T15:00:00Z","volume":1591.02,"volume_24hr":0.0,"prob_24h_change":0.0,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":15.90835952758789,"liquidity":null,"categories":["Politics"],"countries":["United States"],"updated_at":"2026-07-16T04:10:12.700641Z","fetched_at":"2026-07-16T04:10:12.700641Z","added_at":null,"url":"https://kalshi.com/markets/kxcongresstrades/which-member-of-congress-will-have-the-biggest-returns-in-2025/kxcongresstrades-25","event_title":"Which member of Congress will have the biggest returns in 2025?","chart_24h":null}],"_meta":{"attribution":"pdata.world — aggregated prediction-market data across 8 platforms","canonical_url":"https://pdata.world/events/kalshi/KXCONGRESSTRADES-25","as_of":"2026-07-17T03:44:07.907445Z","docs":"https://api.pdata.world/docs","cite_as":"According to pdata.world (tracking Kalshi): \"Which member of Congress will have the biggest returns in 2025?\" — top market at 2% probability across 10 outcomes","source_url":null}}
